Wastewater Treatment and Pretreatment

The Environmental Department operates a regional wastewater treatment plant which consists of 460 acres of lagoons, and 240 acres of wetlands to treat and polish the wastewater. The annual average flow through the headworks is approximately 14 million gallons per day. Currently, Logan City is working on plans to install a mechanical treatment plant to replace our lagoon system. The Purpose of the Environmental Compliance Lagoonback_001Division is to protect the environment, particularly our water resources, by making sure citizens follow the regulations set up by local, state, and federal governments. They are able to adhere to the state and federal standards by promoting reduction of chemical usage, recycling of industrial chemicals, public education, permits, sampling, and inspections of water usage.

The City is in the process of updating the lagoons to a mechanical plant in order to accommodate more stringent ammonia and phosphorous standards as well as future total nitrogen limits. At this time, the City hopes to have construction completed by 2019. To view the most current master plan see below.

Logan City Wastewater Treatment Master Plan with Appendix_Oct15_2015 (38.57 Mb)

Dec06_001Our wastewater treatment system services the communities of:
  • Logan
  • Smithfield
  • Hyde Park
  • North Logan
  • River Heights
  • Providence
  • Nibley
  • Utah State University

To protect the environment, the city’s wastewater collection and treatment systems and the health of its citizens. We aim to do this by keeping the City of Logan in compliance with federal and state environmental regulations on water, wastewater, landfill, mosquito control and household hazardous waste collections.

Dan Dye and Ronald Sims participated in The First International Conference on Algal Biomass, Biofuels & Bioproducts, held in St Louis, Missouri, July 17-20, 2011 where Mr. Dye gave a presentation titled “Combined Photobioreactor Lighting and Electricity Generation.” In addition, Dan Dye and Ronald Sims gave a poster presentation titled “Algae Bioremediation and Biofuels at the Logan, Utah Wastewater Treatment Facility.” Over 300 attendees from over 30 countries participated in the Conference and there was great interest by the participants on what we are doing at the Logan Lagoons to develop large-scale algae production and harvesting processes. Based on the poster that was presented, Dr. Ronald Simms was interviewed at the conference on the topic of the importance of algae bioremediation and wastewater treatment by algae in leading to the success of the algae industry.

OTHER STUDIES Solid Waste and Waste Water News Logan City's Environmental Department and USU's Sustainable Waste-to-Biproducts Engineering Center have partnered to research ways to better deal with our solid waste and waste water. Be sure to check out these short videos that detail this partnership and some of the research that is being done to help our community and others like us.Click here to see a video about how Biological Engineering students and faculty at Utah State University transform waste water into biofuels and other bio-products: 

Pretreatment Programs
The Environmental Compliance Team water pretreatment program involves the following duties:
  • Regulates the disposal of industrial wastewater
  • Protects buildings and safety of personnel
  • Protects the health and safety of the public and the environment
  • Compliance with pretreatment regulations required by local, State, and Federal regulations
  • Prevents illegal discharges to the system through quarterly inspections

  1. Keep the City of Logan in compliance in the areas of Solid Waste, Regional Industrial Wastewaster Pretreatment, and Lagoon Effluent.
  2. Stay current with all local, state, and federal environmental rules and regulations.
  3. Develop environmental policies and procedures for the City of Logan to carry on an effective pretreatment program.
  4. Conduct training for the City of Logan employees, the other cities on our system, industrial users, and the public to enhance environmental awareness.
  5. Construct wetlands as needed to mitigate wetlands impacted by the development of the industrial corridor.
  6. Update Local Limits, Logan City ordinances, and pretreatment enforcement response plan.

The first pretreatment regulations were established in 1972 under the Federal Water Pollution Control Act and in 1977 under the Clean Water Act. These regulations set forth standards mainly for the protection of publicly owned treatment works (POTW). In 1978, the U.S. Environmental Protection Agency (EPA) developed the General Pretreatment Regulations which established mechanisms and procedures for use by state and local pretreatment programs.

Regulate the disposal of wastewater into the sanitary sewerage system. Protect the physical structures of the collection system. Protect the safety of operation and maintenance personnel of the wastewater collection system. Protect Logan City wastewater treatment facility and the receiving water. Comply with all the federal, state and local pretreatment regulations. Protect the health and safety of the public and the environment.

Industries who discharge over 25,000 gallons per day or more of process wastewater, or contribute a process waste stream which makes up 5% or more of the average dry weather hydraulic or organic loading capacity of a treatment plant, or has a reasonable potential to adversely impact the treatment plant or cause a bypass, or damage or obstruct the collection system or personnel.

Categorical businesses (those controlled through 40 CFR regulations), Significant Industrial Users, Restaurants, Auto Repair shops, Car-washes, Auto-body Shops, Radiator Shops, Hospitals, Clinics, Dental Offices, Photo Processors, Labs and other such business. These types of business have received a permit from Logan city Pretreatment Program good for one or more years. They are also subject to quarterly or monthly inspections, sampling and reporting as required on their permit. The purpose of inspection is to obtain information concerning operations, water usage, waste disposal methods, waste streams, chemical usage and storage, spill control and any other pertinent information.

The City has an Enforcement Response Plan (ERP) for all Pretreatment Users. A copy of the ERP is available by calling Jim Harps at (435) 716-9797 or coming to the Environmental Department Building at 153 N 1400 W in Logan.
